Begonia plant named ‘Fiunupwhimp’

ABSTRACT

A new and distinct cultivar of  Begonia  plant named ‘Fiunupwhimp’, characterized by its upright to spreading and mounded plant habit; relatively compact habit; freely basal branching habit; dark bronze-colored leaves; freely and continuously flowering habit; and single-type flowers that are white in color.

Botanical designation: Begonia hybrida.

Cultivar denomination: ‘FIUNUPWHIMP’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia hybrida, and hereinafter referred to by the name ‘Fiunupwhimp’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new compact and uniform Begonia plants with dark-colored leaves and single-type flowers.

The new Begonia plant originated from a cross-pollination made by the Inventor in 2011 of a proprietary selection of Begonia hybrida identified as code number 208193-002, not patented, as the female, or seed, parent and a proprietary selection of Begonia hybrida identified as code number 2314, not patented, as the male, or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Aalsmeer, The Netherlands in 2011.

Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in Aalsmeer, The Netherlands since 2011 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Fiunupwhimp’. These characteristics in combination distinguish ‘Fiunupwhimp’ as a new and distinct Begonia plant:

-   -   1. Upright to spreading and mounded plant habit; relatively         compact.     -   2. Freely basal branching habit.     -   3. Dark bronze-colored leaves.     -   4. Freely and continuously flowering habit.     -   5. Single-type flowers that are white in color.

Plants of the new Begonia can be compared to plants of the proprietary parent selections. Plants of the new Begonia differ from plants of the parent selections in the following characteristics:

-   -   1. Plants of the new Begonia are more uniform than plants of the         parent selections.     -   2. Leaves of plants of the new Begonia are darker in color than         leaves of plants of the parent selections.     -   3. Plants of the new Begonia are more freely flowering than         plants of the parent selections.

Plants of the new Begonia can be compared to plants of Begonia hybrida ‘Fimissmo’, disclosed in a U.S. Plant Patent application filed concurrently, 14/545,695. Plants of the new Begonia differ primarily from plants of ‘Fimissmo’ in the following characteristics:

-   -   1. Plants of the new Begonia have dark bronze-colored leaves         whereas plants of ‘Fimissmo’ have dark green-colored leaves.     -   2. Plants of the new Begonia have smaller flowers than plants of         ‘Fimissmo’.     -   3. Plants of the new Begonia have single-type flowers whereas         plants of ‘Fimissmo’ have double flowers.     -   4. Plants of the new Begonia have white-colored flowers whereas         plants of ‘Fimissmo’ have cream-colored flowers with light         pink-colored margins.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Begonia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant.

The photograph is a side perspective view of a typical flowering plant of ‘Fiunupwhimp’ grown in a container.

DETAILED BOTANICAL DESCRIPTION
